In the selected embodiment of the invention illustrated in the accompanying drawings for purposes of disclosure, there is shown a stenciling apparatus comprising a bed or top plate 8, having supporting end pieces 9, preferably `secured to the under side thereof, and a drawer or container 11, slidably mounted uponsuitable rails k12,

showing one of preferably secured? to the inner sides of the v This end pieces 9, shown `in, Figure 1. drawer provides a suitable and convenient place wherein the necessary tools, such as Y stencils, brushes, paints, waterpots, etc., ina-y be stored, when the apparatus is notv in use, thus keeping them free from dust and eliminating the danger of becoming lost or separated from the device.

When it is desired to usev the apparatus, the drawer 11 may be removed from the rails 12 and placed upon the top of the device, and secured thereto, preferably by means of the opposed angular clips '13, adapted to receive the outwardly projecting ends 14 of the drawer front. When in the above position the operator may readily and quickly select the desired stencil, numerically arranoed therein, and in plain View to the eye. uitable compartments may also be provided at each end of the drawer to receive the necessary tools, etc. a

An inclined plate l5, to which the clips 13 are secured is mounted between suitable end` brackets 16, preferably secured to the ends of the bed 8 by suitable means such las screws 17, to provide a suitable support for* the drawer l1, when in the position shown iii Figure l. A horizontal plate 18 is also preferably -mounted between the brackets 16, and has its topside provided with s uitable trays 19, wherein'the usual paint disks 21 and water pots 22 may be placed for the convenience-of the operator. Referring to Figure 3, it willbenotedxthat an openingr l2O is provided-vat"therear vof the apparatus between the lower rear 'edge of the inclined ioo iio

or streamers of any length which may he'V moved under the brackets and fed conveniently lengthivise'or transversely of the table to change the position of the cards during the stenciling operation. i

lMeans for holding or clamping the'card er other material to be stenciled is provided, land consists of a longitudinal strip or bar 23, pivotally mounted between the end Y b azckets 16, preferably by ineansof suitable pivot pins or screws 24, as shown in Figures 4 and A notch or recess 25 is provided at each end of the bar d3 adapted to receive the coiled tor ion springs 26, mounted upon the pivot pins A24, between the ends ofthe liar and thelnackets 16. Each of these springs have one end secured to the bar 2S while the other end of eachv springr is se cured tok theflirackets v16, in any vsuitable manner. A flexibley guide and clainpiinr ,railV or rule 2"?!y secured tov the forward `cdgeof the bar 23, and projects outwardly therefrom. This rule is forwardly and doivnivardlv inclined and adapted to bear with -a 'yielding- `pressure upon the Acard or material. through the tension of the torsion The rule is preferably made of thin `flexible metal. thereby adapting itself toany irregularities in the surface of the card and'also lirn'ily clamping the card its full Width or length,

depending, of course, upon the manner in which the card is placed upon' the appara'- tus. By referring to Figure 4, it Will also' he noted thatthe rule isformed to provide longitudinal groove 28, extending the entire length of the rule, and 'adapted to receive the edge ofthe' stencil when positioned upon the card,v thereby providing a guide for the stencil and also preventing it from passing under the `clamping rule vvlieiiplaced upon Means for :raising the bar 23 and rule 2 to release the card, isprovided, and consist i ofa shaft or rod 29, rotatably mounted in suitable bea-rings 3l., preferably integral with the end brackets 16. Sockets or recesses are provided in each end of the liar 23, adapted to receive a pair of suit-y able eccentrics 33, mounted upon the shaft. 29, adjacent each end bracket; A flatsurface 34 provided in the upper portion of each recess 32, adapted to be engaged the eccentrics 33, upon rotationof the shaft-9,9.V

Each eccentric is also provided with a lug 35 preferably integralA tliereavith,y auf-l` adapted to engage shoulders 36 in each rc cess, to provide a suitable stop for the eeccntrics when the guide rule 27 is in its uppermost position, shown in Figure Finger grips 3T are provided at each end of the shaft by `means of which the shaft 29 may be rotated. Thus, when the guide and clamping rule 2T is in the position shown in ure 4, and it is desired to release the card or either change its position or remove it from the apparatus, the operator Will rotate either of the finger grips 3T in either one direct-ion or the other, as desired, causing the eccentrics 32 to engage the surfaces 34, thereby raising the bar Q3 and rule 27, until the lugs 35 engage the shoulders 36.

Another important feature of this novel. apparatus resides in the means provided for centering and squaring the card upon the ldevice `With reference to the Vguide and clamping rule 2 A straightl edge slide or' square 38, preferably formed of sheet metal, is adj ustably and slidably mounted upon the bed 8, by n'ieansof depending flanges 39, adapted to be received by correspondingly spaced parallel grooves 4l, provided in the top surface of the bed, adjacent its lforward e'lfr The flanges .39 are oreferably inteliigure 6, andare arranged at substantiizlly right angles ivith reference to the longitudiH nal centerline of the square. Opposedy longitudinal -iia'nges 42 are provide( upon ach side ofthe square, and project outA ivardly therefrom in a horizontal plane and are adapted to slide along the surface ofthe bed 8 when the square is moved thereon.

The square is also provided with vertical.

fla

side Yalls ful, arranged in parallel relaiion,

against which the card or sheet of material to be' stenciled is placed to be squared, as clearly `indicated in Figure 7.

Referring to the above figure, and also to i Figure 2, it'Will be notedthat a'poitien of the horizontal"flanges's'is cut away adJ jacent the inner end of the Square, thereby providing opposed outwardly extending lugs 44. rEhe flanges` 42 and lugs 44 are adapted to rest jupon the surface of the bed S, and functions inpreveiiting the card or other material from slipping under the square lwhen placed thereagainst.

Means for centering the card upon the hed 8 is shown in Figures 2 and 7. A centering linark 45, preferably in the forni of an arroiv, is inscribed in the top surface of the bar 23, an equal distance from each end of the apparatus. A centering or master scale 4G, pref erably of ivood, is provided beneath this arrouv and is preferably imbedded o inlaid in the surface of the lied, shown in Figure `3, thus Vproviding` smooth surface loyer which the card may slide Yvaitliout interfer- @lli This master scale hasA ai' plurality of jfioi individual scales, preferably threein numbeifinscribed thereon, and also a line, here` inafter referred to,as the "top of type lined.

rlhe 4upper scale 1li' is preferably numbered from rightto left while 'the middle. scalegiS is arranged in reversed relation, numbering.; from yleft to right. '.lhes'e' scales. V may be divided into any number of equal divisions, as desired, and mayA also be arranged in reverse relation to that shown, i. e., the upper scale. numbering from left to right and the middle scale from right to left. 'llhe lop of type linel is. represented by a heavy broken line e9, also inscribed in the suri'ice of tlm. master scaleilG. rihis line is spared a fixed distance from the bottoni of the groove 28, when the rule 2i in its clamping' position, said distance corresponding 'to the disw tance between the edge of the stencil andfthe top of the, type. or chffiracter provided therein, as clearly irulicated by the light dotted line in Figure 7. rivthird or lower scale 51 is also provided and is preferably graduated in such a Vmanner as to correspond to cards of standard widths, usually ranging; in sizes from 51/2 and upward. The stencil S also has letter indexes 52 thereon arranged in the upper and lower corners thereof to enable f the user to determine `where to begin the first letter on the cardso that the inscription, when finished will be uniformly centered.

Operations-Flic operation of this apparatus may be explained in the following manner with reference to Figure 7.

The card or sheet of paper to be stenciled is placed upon the bed 8 and centered thereon by means of the scales i7 and e8. This is accomplished by moving,` the card along on the bed until the two ends of 'the card will register correspondingly upon the scales 47' and d8, or will register like numerals, as is clearly indicated in the above figure. The square 38 is then moved up to the card until the end of said card engages one of the ver tical walls 113 of the. square, the flange 42 and lugt passing under the card as shown. soon as the card has been centered and squared as above described, the. bar 223 will be released by means of the liugjer'grips 37 and the guide and clamping;` rule Q7 `will engage the surface of the card, thereby firmly holding.;l it in the proper position.

The operator will then select the desired stencil and place it upon the card with its upper edge bearing?T against the bottom of the groove 28. As soon as the operator has computed the number of letters to be stenciledin a line, incliuling` spaces,- etc., he will place the stencil upon the card, as above described, with the numeral in the index 52, correspondino' to the number of letters in the line to be stenciled, directly beneath the point of the arrow, as indicated in Figure 7. ln this ligure it will be noted that the numeral 8 is in line with the arrow, indicating` that eight. letters or characters will be required to complete the line. Wlhen the stencil is in the above position, the operator will place a small mark 53 upon the card, using; the end of the stencil as a guide. This is preferably done with a pencil, and` represents the starting point of the firstlettcr in the line. The stencil 'is then moved to the left until thel nearest point of the opening in the stencil, represei'itiue' the desired letter, touches the mark 53. Should this be a complete letter, as in the case ofthe letters C and E, the entire letter may be stenciled without meving` the stencil,'but should it be a letter'suclh as A or B,'the diagonal or 'vertical portion of the letter would be stenciled first and the stencil moved to complete the letter.

Thus, by the use of this novel apparatus, cards and sheets of paper or other material may be quickly and accurately stenciled without loss of time, and when completed will have the appearance of being hand painted, all letters beine' solid and unbroken as indicated` by the word Best in Figure This device may Ytlmrefore be universally used asa stencilingappafatus.V`
